Put this in one of my two identical Fender Champion 600s and A/B'd them against each other. At first, the difference was marginal. But... After using my looper to play guitar through the speaker at high volume for eight or more hours, the difference was palpable.
The lows are much tighter and less flabby, and the high notes or more distinct and clear.
Great improvement over stock!
Used the Mod 6-15 speaker to replace the factory speaker in my Fender Champ 600. What a huge improvement. I would also suggest changing the factory grill cloth when you change the speaker for an even greater sound improvement.
Same here. I bought the Mod6-15 Jensen to replace the crappy speaker that comes with the Fender 600 champion. Great improvement. The shipping was also very fast. I will purchase here again.
